摘要
研究灰岩在不同温度作用后进行单轴压缩时的声发射特征。通过试验得到灰岩破坏全过程中应力-声发射数量曲线。试验结果表明:声发射现象能很好地表现岩石单轴压缩的过程;高温下,灰岩的力学性质与岩石所含矿物质含量有密切关系。
Learn the experimental study of acoustic emission characteristics during uniaxial compression of limestone under different temperature. Through the test, get the stress-the number of acoustic emission curve of the whole process of rock failure. The results showed that： acoustic emission phenomenon can show the process of the rock uniaxial compression. The peak strength of the limestone which is at high temperatures tends to decrease overall with the temperature increasing. Mechanical properties of limestone is closely related to the content of the mineral under high temperature.
